Just a reminder for anyone thinking of travelling to Sochi after the Olympics for a spot of tourism: according to Russia's deputy prime-minister, the hotel bathrooms have surveillance cameras that watch you in the shower.

“We have surveillance video from the hotels that shows people turn on the shower, direct the nozzle at the wall and then leave the room for the whole day,” he said. An aide then pulled a reporter away before Mr. Kozak could be questioned further on surveillance in hotel rooms. “We’re doing a tour of the media center,” the aide said.
